第一種
<!DOCTYPE html>
<html encoding="utf-8">
<head>
<style>
*{margin:0;padding:0}
input{font:14px Monospace;height:20px;width:160px;}
label{display:inline-block;width:100px;height:20px;}
#pass{position:absolute;left:100px;top:0;opacity:0;filter:alpha(opacity=0);z-index 第二種 登入可見密碼實現
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
body{
margin:0px;
background-color: white;
font-family: 'PT Sans', Helvetica, Arial, sans-serif;
text-align: center;
color: #A6A6A6;
}
/*輸入框樣式，去掉背景陰影模仿原生應用的輸入框*/
input{
width: 100%;
height: 50px;
border:none;
padding-left:3px;
font-size: 18px;
}
input:focus {
outline: none;
}
/*顯示隱藏密碼圖片*/
img{
width: 40px;
height: 25px;
position: absolute;
right: 0px;
margin: 15px;
}
/*登入按鈕*/
button{
width: 200px;
height: 50px;
margin-top: 25px;
background: #1E90FF;
border-radius: 10px;
border:none;
font-size: 18px;
font-weight: 700;
color: #fff;
}
button:hover {
background: #79A84B;
outline: 0;
}
/*輸入框底部半透明橫線*/
.input_block {
border-bottom: 1px solid rgba(0,0,0,.1);
}
/*container*/
#page_container{
margin: 50px;
}
</style>
</head>
<body>
<div id="page_container">
<!--暗文密碼輸入框-->
<div class="input_block" id="psw_invisible">
<img id="visible" onclick="showPsw()" src="visible.png">
<input type="password" id="input_invisible" placeholder="Password"/>
</div>
<!--明文密碼輸入框-->
<div class="input_block" id="psw_visible" style="display: none;">
<img id="invisible" onclick="hidePsw()" src="invisible.png">
<input type="text" id="input_visible" placeholder="Password"/>
</div>
<button onclick="">Login</button>
</div>
<script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.js"></script>
<script type="text/javascript">
// 這裡使用最原始的js語法實現，可對應換成jquery語法進行邏輯控制
var visible=document.getElementById('psw_visible');//text block
var invisible=document.getElementById('psw_invisible');//password block
var inputVisible = document.getElementById('input_visible');
var inputInVisible = document.getElementById('input_invisible');
//隱藏text block，顯示password block
function showPsw(){
var val = inputInVisible.value;//將password的值傳給text
inputVisible.value = val;
invisible.style.display = "none";
visible.style.display = "";
}
//隱藏password，顯示text
function hidePsw(){
var val=inputVisible.value;//將text的值傳給password
inputInVisible.value = val;
invisible.style.display = "";
visible.style.display = "none";
}
</script>
</body>
</html>對第二種，html、js改進
<body>
<textarea type="password"></textarea>
<div id="page_container">
<!--密碼輸入框-->
<div class="input_block">
<img id="demo_img" onclick="hideShowPsw()" src="visible.png">
<input type="password" id="demo_input" placeholder="Password"/>
</div>
<button onclick="">Login</button>
</div>
<script type="text/javascript">
// 這裡使用最原始的js語法實現，可對應換成jquery語法進行邏輯控制
var demoImg = document.getElementById("demo_img");
var demoInput = document.getElementById("demo_input");
//隱藏text block，顯示password block
function hideShowPsw(){
if (demoInput.type == "password") {
demoInput.type = "text";
demo_img.src = "invisible.png";
}else {
demoInput.type = "password";
demo_img.src = "visible.png";
}
}
</script>
</body>
